MACHINE FOR CLEANING BUCKWHEAT, &C.

Specification of Letters Patent N o.

To all whom it may concern:

Be it known that I, JOHN I-I. REED, of Penn township, in Clearfieldcounty, in the State of Pennsylvania, have invented a new and ImprovedMachine for Scouring and Cleaning' Buckwheat and other' Grains; and Ihereby declare that the following is a full and exact description.

The nature of my invention is causing a cylinder on which is cut.spirally a triangular shaped groove gradually diminishing from thefeeding place to place of discharge, to revolve in a hollow cylinderwhich is supplied at or near the one end with a hopper for feeding andat the other with a discharge passage.

In order to enable others who might desire to manufacture oruse myinvention I will proceed to describe it. I make of iron or any suitablesubstance a cylinder marked in the accompanying drawing (Z on which iscut or cast a triangular' shaped groove so arranged that the grooveshall constantly diminish from the point where the grain enters to themachine in the place where it is discharged. On either end of thiscylinder is a gudgeon, supplied at one end with a pulley marked indrawing and used for the application of power to the machine, and at theother end with a pulley marked in drawing e to be used for attaching fanor some other device for removing dust &c. I also make an outer cylindermarked in drawings c and f the diameter' of the bore of which equals thediameter of the cylinder 1narked.cZ, which is intended to revolve29,940, dated September 4, 1860.

therein, this cylinder to be closed at each end and to be ofsufiicientlength to contain the one first named. It is supplied with a hoppermarked in drawings a through which the grain is conducted into themachine and by means of the triangular groove is conducted to anotheropening or discharge place marked in drawings g, with which the cylinderis supplied,

Then grain is placed in the hopper and the supply continued, thetriangular' shaped groove conducts the grain from feeding place to placeof discharge, the machine being in motion; from the shape of the grooveand the fact that it is constantly diminishing in size, the gra-inschange position and rub against each other and thus scour and cleansethemselves.

I do not claim one cylinder revolving in another, nor such anarrangement as will merely conduct the grain from one place to another,but the constantly diminishing groove through which the grain must pass`I therefore claim as my invention- One cylinder revolving in another,the inner or revolving cylinder so grooved that while conducting thebuckwheat or other grain from the place of feeding to the place ofdischarge the grain shall pass through a regularly diminishing space andthus be scoured or cleaned, as above set forth.
